Product details
Overview
74ALVC541PW,118 from Nexperia is an octal non-inverting 3-state buffer/line driver with dual active-low output enables (OE0 and OE1), Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operation across 1.65 V to 3.6 V supply. It delivers 2.3 ns typical propagation delay at 3.3 V and supports industrial-temperature operation from −40 °C to +125 °C in TSSOP20 packaging. Used in bus interface isolation and level translation between mixed-voltage logic domains.
For engineers reviewing the 74ALVC541PW,118 datasheet, 74ALVC541PW,118 pinout, 74ALVC541PW,118 application, or 74ALVC541PW,118 equivalent, key selection criteria include dual OE control timing, IOFF-enabled hot-swap compatibility, Schmitt-trigger input hysteresis, 3.6 V overvoltage-tolerant inputs, and TSSOP20 thermal performance under 125 °C ambient conditions.
Technical Context
This device implements eight independent non-inverting buffers, each with separate output enable control via OE0 (pins 1 & 19) - enabling grouped channel activation. Its IOFF circuit actively disables outputs and blocks backflow current when VCC = 0 V, satisfying JEDEC JESD78 Class II.A latch-up robustness (>250 mA) and supporting live-insertion systems.
Schmitt-trigger inputs provide ≥0.35 × VCC hysteresis (e.g., 1.26 V at VCC = 3.6 V), allowing reliable operation with slow-rising signals. Static drive strength is specified at ±24 mA (VOL ≤ 0.55 V, VOH ≥ 2.2 V at VCC = 3.0 V), and dynamic performance includes 3.5 ns max tpd and 5.6 ns max ten at 3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 3.6 V - Enables direct interfacing between 1.8 V, 2.5 V, 3.3 V logic families without level shifters. |
| Propagation Delay (tpd) | 3.5 ns max at VCC = 3.6 V - Supports >140 MHz data rates in point-to-point buffered paths. |
| IOFF Leakage Current | ±80 μA max at VCC = 0 V - Prevents damaging backfeed during partial system power-down or hot-plug events. |
| Input Hysteresis | ≥0.35 × VCC - Ensures clean switching on noisy or slow-transitioning control/data lines (e.g., pushbutton debouncing, long PCB traces). |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Drives 50 pF loads with <3.5 ns edge times while maintaining VOL ≤ 0.55 V and VOH ≥ 2.2 V. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O, and high-ambient embedded controllers. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Reduces need for external ESD suppression in board-level designs. |
Pinout & Package
TSSOP20 package (SOT360-1): 20-terminal plastic thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, 0.8 mm max height - optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE0, OE1 | Active-low output enables - independently disable Y0–Y7 (OE0) or Y0–Y7 (OE1); both must be LOW for outputs to drive. |
| 2–9 | A0–A7 | Non-inverting data inputs - accept 0–3.6 V logic levels regardless of VCC; Schmitt-triggered for noise margin. |
| 10 | GND | Ground reference - decoupling capacitor placement critical for noise suppression in high-speed switching. |
| 11–18 | Y0–Y7 | 3-state buffered outputs - present high-impedance (Z) when either OE is HIGH; drive LOW/HIGH per input when enabled. |
| 20 | VCC | Power supply - requires local 100 nF ceramic decoupling; IOFF remains active even if VCC drops to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent output enables | OE0 and OE1 allow selective activation of all eight outputs as one group - simplifies bus arbitration and reduces control-line count vs. individual gating. |
| IOFF partial power-down protection | Automatically disables outputs and blocks reverse current flow when VCC = 0 V - essential for PCIe add-in cards, modular backplanes, and hot-swap subsystems. |
| Schmitt-trigger inputs | Input hysteresis ≥0.35 × VCC eliminates metastability from slow edges - eliminates need for external RC filtering on reset, interrupt, or configuration lines. |
| Overvoltage-tolerant inputs | Accept up to 3.6 V regardless of VCC setting (1.65–3.6 V) - enables safe interfacing with legacy 3.3 V peripherals driving into 1.8 V domains. |
| JEDEC-compliant voltage ranges | Fully compliant with JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.5 V), and JESD8C/JESD36 (2.7–3.6 V) - guarantees interoperability across industry-standard logic families. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC541APWR | TI part with identical pinout, same 1.65–3.6 V range, but lower IOFF leakage (±10 μA vs. ±80 μA) and no Schmitt inputs. | Lacks input hysteresis - requires clean, fast-rising signals; better suited for controlled FPGA-to-ASIC interconnect than noisy industrial environments. | Select when Schmitt triggering is unnecessary and tighter IOFF control is required for ultra-low-power sleep states. |
| 74LVC541AD,118 | Nexperia SO20 variant (SOT163-1); same electrical specs but larger footprint, higher thermal resistance (12.3 mW/K derating above 109 °C vs. 10.0 mW/K for TSSOP). | Preferred for prototyping or legacy through-hole-compatible boards; less suitable for space-constrained automotive modules. | Choose for manual soldering, thermal testing, or compatibility with existing SO20 footprints where board real estate is not constrained. |
Compared with SN74LVC541APWR, the 74ALVC541PW,118 offers superior noise immunity via Schmitt inputs and higher IOFF tolerance, while the 74LVC541AD,118 trades miniaturization for easier handling and thermal margin in non-density-critical designs.

FAQ
What is the function of the two output enable pins (OE0 and OE1) on the 74ALVC541PW,118?
OE0 (pin 1) and OE1 (pin 19) are independent active-low enables controlling the same set of eight outputs (Y0–Y7). Both must be LOW for outputs to drive; if either is HIGH, all outputs enter high-impedance state. This dual-enable architecture supports redundant control signaling or fault-safe shutdown in safety-critical systems.
Does the 74ALVC541PW,118 support hot-swap or live-insertion applications?
Yes - its IOFF circuitry actively disables outputs and blocks reverse current flow when VCC = 0 V, meeting JEDEC JESD78 Class II.A latch-up immunity (>250 mA). This enables safe insertion/removal in powered backplanes, modular servers, and telecom line cards without risking damage to upstream drivers.
Can the 74ALVC541PW,118 interface between 1.8 V and 3.3 V logic domains without external level shifters?
Yes - its overvoltage-tolerant inputs accept up to 3.6 V regardless of VCC (1.65–3.6 V), and its outputs swing rail-to-rail. When powered at 1.8 V, it safely receives 3.3 V inputs; when powered at 3.3 V, it drives 3.3 V–compatible loads - eliminating discrete level translators in many mixed-voltage designs.
How does the Schmitt-trigger input improve system reliability compared to standard CMOS inputs?
Schmitt-trigger inputs provide hysteresis (≥0.35 × VCC), meaning the threshold for rising edges is higher than for falling edges. This rejects noise spikes and prevents multiple transitions on slow-rising signals - critical for pushbuttons, long cables, or inductive sensor outputs where signal integrity cannot be guaranteed by layout alone.
